SPECIFICATION forming part of Letters Patent No. 526,714, dated October 2, 1894. Application filed October 2, 1893. i Serial No. 486,940 (No model.)

To all whom it may concern:

Be it known that we, FITZ A. KIRBY and JAMES HENNING, citizens of the United States, residing at \Wyandotte, county of Wayne7 State of Michigan, have invented certain new and useful Improvements in Flanging-Machines; and we declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

Ourinvention has for its object a cold plate Hanging and angle opening and closing machine, of superior construction and efficiency and it consists of the construction, combination and arrangementof `devices and appliances hereinafter described and claimed, and illustrated in the accompanying drawings, in which- Figure l is a side elevation. Fig. 2 is an end elevation looking toward the Hanging rolls on the left of Fig. 1. Fig. 3 is a View of the opposite end. Fig. 4 is a plan View. Fig. 5 is a detail View in vertical section through the Hanging rolls b2 and 57 on the shafts B and B2. Fig. 6 is a detail view in vertical section through one of the nuts of one of the screw shafts. Fig. 7 is a detail in vertical section through the bushing of the operating shaft, and adjacent bearing.

Our invention is especially adapted and designed to provide an improved Hanging machine for Hanging metal plates, used in shipbuilding, although we do not limit ourselves to any definite purpose to which the machine may be applied. It is well understood that in ship-building, metal plates are required to be Hanged in various ways and in various forms. Our invention contemplates a machine capable of straight plate Hanging, also for forming Hanges of hollow or rounding forms, and also by which a Hange may be bent at any desired angle, closing or opening at any desired bevel, and by which the angle can be varied, as desired, as the plate passes through the machine.

To these ends we carry out our invention, as follows:

A denotes any suitable supporting frame which may be provided with stay-rods a extending longitudinally of the machine.

The frame is constructed with housings A and A2 in which are shown engaged lower rotatable shafts B and B', upon each of which is mounted a series of Hanging rolls b, IJ', b2, between the housings, and Hanging rolls b3, on one extremity of each shaft outside the adjacent housing. The lower shafts are shown immovable vertically. Above the shafts B, B are located corresponding shafts B2 and B2,`each provided with corresponding Hanging rolls b4, b5, 126 between the housings, and with a Hanging roll 127 outside the housing, the latter corresponding to the Hanging roll b2 there-beneath. One upper shaft with the lower shaft there-beneath, provided with the Hanging rolls thereupon, form a set, two sets being shown, the one at the right hand i and the other at the left hand in Fig. 2. The

upper and lower shafts are also provided, preferably, at their outer extremities opposite the Hanging rolls bs and Z7?, with straightening rolls bs and b9.

C is a driving shaft which may be provided with a gear C', said gear meshing with gears B4 and B5 upon the two lower shafts B, B respectively. The gear B5 meshes with a gear B6 on the corresponding upper shaft B3, and the gear B4 meshes with a gear B7 on the corresponding upper shaft B2. We do not, however, limit ourselves to any specific mechanism for driving the shafts with their Hanging rolls.

The uppermshafts B2 and B2, with their Hanging rolls, are shown as made vertically movable. To this end they are each provided with bearings A3 and A4, atthe forward end, and with similar bearings at A5 and A, at their opposite ends, said bearings being vertically movable in suitable elongated orifices a', in the housing. Connected with each of these bearings is a screw threaded shaft D, D', D2 and D8, respectively. These screw threaded shafts are provided toward their upper ends with corresponding nuts d, d', d2 and d2, in which the corresponding screw threaded shafts work. With the nuts, are engaged corresponding adjusting gears E, E',

ICO

away to show the gear E2. The worm gear H meshes with one of the adjusting gears on the corresponding nut, which gears mesh one with the other. The worm gear H2 meshes with one of the adjusting gears at the opposite end of the machine, which said gears also mesh the one with the other.

The operating shaft H may be provided with a hand wheel, or other suitable device preferably at each end thereof, as shown at H3. Obviously, the two screw shafts, at each end of the machine, will be constructed ther one with right hand and the other with left hand screw-threads. per set of-rolls may be readily adjusted vertically in a convenient and speedy manner.

It will be evident that by removing the wrenches Gr, G', the screw shafts can be properly adj usted in their corresponding nuts to suit the work, when the wrenches may be reapplied. By turning one of the handwheels H3, Vboth of the upper sets of hanging rolls may be vertically adjusted simultaneously. The left hand upper hanging roll, 'L'. e., roll o7 on the shaft B3 needs to be turned down a little lower than the corresponding upper roll in front thereof, in operation, to make ythe two rolls each do their work successively. The work will be introduced to the hanging rolls b2, 197 from the right hand of Fig..2.

To `throw the operating shaft H and its worm gear out of mesh with the adjacent adjusting gears upon the nuts d, CZ', d2, d3, the operating shaft may be provided with a bushing .T within the bearing J', of said shaft, the bushing being eccentrically connected with theI operating shaft within the bearing. It will be evident that by turning this bushing about on either end of the Operating shaft, either or both corresponding worm gears will be thrown into or out of mesh with the corresponding adjusting gears. lbushing may be operated for this purpose in any suitable manner. For example, the bearing J may be constructed with an elongated arc-shaped slot j and the bushing be provided with a bar or lever j passing through said slot, whereby the bushing may be rotated, the ends of said slot limiting the rotation of said bushing.

For hollow and round hanging, the two left hand hanging rolls h2 and 197, of Fig. 2, forming one set of rolls, should be loosely mounted By this means the up! The upon their corresponding shafts B', B3, and constructed to have alongitudinal playthereupon corresponding to the curve of the harige, as indicated in Fig. 5. For straight hanging, no longitudinal movement is required.

Our hanging machine, as above observed,

is designed and adapted especially for hanging metal plate, cold. It is well understood that the heating of such plates, to flange them, injures the plate, and that hanging them cold by hand, in the ordinary manner, is a very slow process. By our invention, however,the plates can be hanged cold in a very efficient and speedy manner. To get the degree of hanging required, or the desired angle, it `will be necessary to run the plate several times through the machine, tightening down the outer upper hanging rolls at each time the plates are run therethrough. Usually the plates will be marked on a line at which the flange is to be bent, and we design to provide ythe outer frame with an indicator hnger Q to facilitate the guiding of the plate through the rolls on the line so marked. Y

It will be perceived that the V-rolls are on the lower shafts, as shown in the drawings, but the arrangement might be reversed within the scope of our invention. The hanging rolls between the uprights of the frame are designed more particularly for shaping angle iron to required forms. While we have shown two sets of lower and upper shafts, with their hanging rolls, the machine would be operative with a single set of rolls, that is, asingle lower shaft with a single upper shaft with their corresponding rolls.

It will be perceived that the V-shaped hanging rolls exert their pressure to effect the desired hanging, on the line previously laid out, as above described, at the apex of the angle to be formed. For dierent thicknesses of plate it will be found desirable to substitute, upon the corresponding shafts, hanging Arolls of suitable form in order not to exert too severe a pressure upon the plate. The outer hanging rolls therefore canv be made removable so that any desired form of roll may be applied upon the corresponding shaft to suit the work required.

The threaded shafts D-, D', D2 and D3 are shown constructed with spherical heads at their lower ends correspondingly seated in the bearings A3, A4, A5 and A6. This forms a ball and socket joint at this point of construction. One set of hanging rolls is made V- shaped meshing with the corresponding rolls of inverted V-shape.
